OpenClaw safeBins stdin-only bypass via sort output and recursive grep flags
Summary
tools.exec.safeBins could be bypassed for filesystem access when sort output flags (-o / --output) or recursive grep flags were allowed through safe-bin execution paths.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.17 - Patched versions:
>= 2026.2.19 - Latest published version at triage time:
2026.2.17
Impact
In deployments that enabled tools.exec.safeBins, an attacker with access to command execution flows could turn intended stdin-only safe-bin usage into file writes (sort -o) or recursive file reads (grep -R).

Связанные уязвимости
OpenClaw versions prior to 2026.2.19 tools.exec.safeBins contains an input validation bypass vulnerability that allows attackers to execute unintended filesystem operations through sort output flags or recursive grep flags. Attackers with command execution access can leverage sort -o flag for arbitrary file writes or grep -R flag for recursive file reads, circumventing intended stdin-only restrictions.
